Next week, I will be surveying 8 sites, each with about 20-30 Variable Refrigerant Units. I will not have access to a front-end, and am looking for a way to force each unit into a cooling mode to calculate the superheat.
Ideally, I would like to find a device that I could attach to a wall sensor to temporarily raise the temperature, theoretically throwing the unit into cooling. Something like a handwarmer is what I had in mind.
Does anyone know of such a device, or does anyone have other suggestions on how to accomplish my goal?
Thanks in advance.
